Factors Involved in Delaying Initiation of Adjuvant Chemotherapy After Breast Cancer Surgery.

BACKGROUND: Delays in initiating adjuvant chemotherapy after breast cancer surgery seems to have an impact on patients' risk of relapse and their survival rate. The aim of this retrospective study was to identify factors delaying initiation of adjuvant chemotherapy after breast surgery. MATERIAL AND METHODS: All patients undergoing surgical treatment for mammary cancer between June 2014 and June 2015 and receiving adjuvant chemotherapy were selected retrospectively. RESULTS: In multivariate analysis, 3 factors significantly delay initiation of adjuvant chemotherapy: a secondary procedure (odds ratio [OR], 6.67; P = .00012), inclusion in a therapeutic trial (OR, 8.46; P = .0013), and a positive HER2 status (OR, 3.02; P = .063 [statistically significant]). DISCUSSION: This study provides a brief overview of the population most likely to experience a delay in the initiation of their adjuvant chemotherapy after cancer surgery. Our findings should assist interventions during initial management.

[Sentinel node detection using optonuclear probe (gamma and fluorescence) after green indocyanine and radio-isotope injections]. / Détection du ganglion sentinelle dans le cancer du sein par sonde opto-nucléaire après injection de vert indocyanine et de technétium 99m.

OBJECTIVE: Assess the biopsy's feasibility of the sentinel lymph node biopsy (SLNB) using optonuclear probe after of indocyanine green (ICG) and radio-isotope (RI) injections. METHODS: Twenty-one patients with a localized breast cancer and unsuspicious axillary nodes underwent a SLNB after both injections of ICG and radio-isotope. RESULTS: One or more SLN were identified on the 21 patients (identification rate of 100%). The median number SLN was 2 (1-3). Twenty SLN were both radio-actives and fluorescents (54.1%), 11 fluorescent only (29.7%) and 6 were only radio-actives (16.2%). Seven patients had a metastatic SLN (8 SLN overall). Among them, only one had a micrometastasic SLN, 5 others had a macrometastatic SLN and one patient had two macrometastatic SLNs. Among the 8 metastatic SLN, 5 were both fluorescent and radioactive, 2 were only fluorescent and 1 was only radioactive. CONCLUSION: Detection SLN using optonuclear probe after indocyanine green and radio-isotope injections is effective and could be, after validation by randomized trial, a reliable alternative to the blue dye injection for teams who consider that combined detection as the reference.

[Follicular dendritic cell sarcoma in head and neck region]. / Sarcome à cellules folliculaires dendritiques de la région ORL.

Follicular dendritic cell sarcomas are a recently described entity, with biphenotypic characteristics of lymphomas and sarcomas. The treatment is hardly consensual in the literature. We report two head and neck cases, of favorable outcome after surgery and radiotherapy. Histopathology and differential diagnoses are discussed as well as the therapeutic strategies used.

Prognostic impact of tumour multifocality in thyroid papillary microcarcinoma based on a series of 160 cases.

OBJECTIVE: The objective of this study was to evaluate the prognostic impact of tumour multifocality in papillary thyroid microcarcinoma (PTMC). METHODS: All patients who underwent total thyroidectomy and central neck dissection for PTMC in our institution between 1990 and 2007 were included in this retrospective study. Statistical correlations between tumour multifocality and various clinical or pathological prognostic parameters were assessed by univariate and multivariate analyses. RESULTS: A total of 160 patients (133 women and 27 men; mean age: 47.8±13.7 years) were included in this study. Tumour multifocality was demonstrated in 59 (37%) patients. Central neck metastatic lymph node involvement was identified in 46 (28%) patients. No statistical correlation was demonstrated between tumour multifocality and the following factors: age, gender, tumour size, extension beyond the thyroid, metastatic central neck lymph node involvement and risk of recurrence. A tumour diameter greater than 5mm was associated with a higher risk of recurrence (P=0.008). CONCLUSION: Tumour multifocality does not appear to have a prognostic impact in PTMC.
